will a broody?

Sit on eggs even if they have gone bad or will she kick them out?

my broody sat on an egg that never developed. I took it and cracked it open a day or so after all the other eggs hatched and it was just goo inside. My other broody sat on an egg that was bad till after the others hatched and then kicked that egg out of the nest.
